Summary Description Blaise is an integrated system designed for efficient collection, editing and analysis of survey data. In its present state it is a powerful and flexible system for computer assisted survey processing. Therefore the scope of Blaise is wider than just data collection. Based on a formal survey definition, the Blaise system automatically generates programs for computer assisted face-to-face interviewing with laptop computers (CAPI: Computer Assisted Personal Interviewing), for Computer Assisted Telephone Interviewing (CATI), for Computer Assisted Self-Interviewing (CASI) and for interactive entering and editing of data collected on paper forms (CADI: Computer Assisted Data Input) for various data manipulation facilities and has full survey management capabilities. With Blaise one can perform various activities in an easy and user-friendly way. For the analysis of data files, Blaise can create descriptions of a Blaise data model for use by other software packages such as SAS, SPSS, Stata, Paradox and Oracle. In addition, users can define additional setups and system files of their own choice. Future releases of Blaise will be more and more "open", using a.o. component-based technology. Though Blaise was initially designed for interviews among persons and households it nowadays has developed into a tool with a much broader scope that can be used for all kinds of surveys, among enterprises as well. Blaise is used world wide by many types of survey organisations including government institutions, universities, and private research foundations.
